I guess with the creation of phrases like "emotional IQ" and "cognitive IQ" even the research expressed its doubt that those tests can truly hold their promises. Freerk Huisken might be right in the end. He argued that it's a logical problem when one is trying to measure intelligence in artificial test as they can not retrieve the true capabilities of a human. Intelligence is a damn complicated subject and although we humans love to measure and categorize everything, we should consider that IQ tests are far from being comparable. Truth is, we still do not understand what intelligence actually is :)
This is actually a nice topic to discuss with philosophers.
